Hello,

every time when booting 4.0-rc6 kernel I see those error messages in dmesg log:

[    1.836306] [drm:hsw_unclaimed_reg_detect.isra.10 [i915]] *ERROR* Unclaimed register detected. Please use the i915.mmio_debug=1 to debug this problem.

lspci show card as:
00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06)

Do you know what it means? What are those errors?

And every time when I open LID of my notebook i915 driver write lot of messages to dmesg:

[   62.015885] i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment

[   62.025206] i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment

(closing LID do nothing - no suspend or hibernate action)

Problem with those messages when opening LID I already reported to bug:
